Yadda ake Ƙara Sabbin Disks Ta Amfani da LVM zuwa Tsarin Linux ɗin da yake

rabu ko ya rabu.

Wasu daga cikin sharuɗɗan da kuke buƙatar fahimta yayin amfani da LVM:

  • Ƙarar Jiki (PV): Ya ƙunshi Raw disks ko tsararrun RAID ko wasu na'urorin ajiya.
  • Rukunin Ƙirar (VG): Yana haɗa juzu'i na zahiri zuwa ƙungiyoyin ajiya.
  • Logical Volume (LV): VG's an raba su zuwa LV's kuma ana hawa a matsayin partitions.

A cikin wannan labarin, za mu ɗauke ku ta hanyar matakai don saita Disks ta amfani da LVM a cikin injin Linux na yanzu ta hanyar ƙirƙirar PV, VG's da LV's.

Lura: Idan ba ku abin da za ku yi amfani da LVM ba, zaku iya ƙara faifai kai tsaye zuwa tsarin Linux ɗin da ke akwai ta amfani da waɗannan jagororin.

  1. Yadda ake Ƙara Sabon Disk zuwa Tsarin Linux
  2. Yadda ake Ƙara Sabon Disk Ya Fi Girma 2TB zuwa Tsarin Linux

Bari mu yi la'akari da yanayin inda akwai 2 HDD na 20GB da 10GB, amma muna buƙatar ƙara kashi 2 kawai ɗaya na 12GB da wani 13GB. Za mu iya cimma wannan ta amfani da hanyar LVM kawai.

Da zarar an ƙara faifai, zaku iya jera su ta amfani da umarni mai zuwa.

# fdisk -l

1. Yanzu partitions biyu disks /dev/xvdc da /dev/xvdd ta amfani da umarnin fdisk kamar yadda aka nuna.

# fdisk /dev/xvdc
# fdisk /dev/xvdd

Yi amfani da n don ƙirƙirar ɓangaren kuma adana canje-canje tare da umarnin w.

2. Bayan rabuwa, yi amfani da umarni mai zuwa don tabbatar da sassan.

# fdisk -l

3. Ƙirƙirar Ƙarar Jiki (PV).

# pvcreate /dev/xvdc1
# pvcreate /dev/xvdd1

4. Ƙirƙiri Ƙungiya Ƙarfafa (VG).

# vgcreate testvg /dev/xvdc1 /dev/xvdd1

Anan, \testvg shine sunan VG.

5. Yanzu yi amfani da \vgdisplay don lissafa duk cikakkun bayanai game da VG's a cikin tsarin.

# vgdisplay
OR

6. Ƙirƙirar Ƙirar Ma'ana (LV).

# lvcreate -n lv_data1 --size 12G testvg

8. Tsara madaidaicin juzu'i (LV's) zuwa tsarin ext4.

# mkfs.ext4 /dev/testvg/lv_data1
# mkfs.ext4/dev/testvg/lv_data2

9. A ƙarshe, hawan tsarin fayil.

# mount /dev/testvg/lv_data1 /data1
# mount /dev/testvg/lv_data2 /data2

Tabbatar ƙirƙirar kundayen adireshi data1 da data2 kafin hawa tsarin fayil.

Shi ke nan! A cikin wannan labarin, mun tattauna yadda ake ƙirƙirar bangare ta amfani da LVM. Idan kuna da wata tsokaci ko tambaya game da wannan, jin daɗin yin post a cikin sharhi.
